Global dry natural gas production increased 110% between 1980 and 2010, from 53 trillion cubic feet (Tcf) in 1980 to 112 Tcf in 2010. The combined share of North America and the Former Soviet Union—the top two producing regions during the time period—fell from 72% in 1980 to 49% in 2010. While all regions increased natural gas production between 1980 and 2010, the Middle East grew most rapidly, increasing more than eleven-fold.
